SAFETY LATCH Filed Jan. 10, 1944 2 Sheets-Sheet 1 INVENTOR. farm; S/mfh1? Patented Sept. 14, 1948 Aaron Shatkin, Matawan, N. J. ApplicationJanuary 10, 1944, Serial No. 517,647 I 6 Claims.

The present invention relates to latches par- I ticularly adaptable toarticles of jewelry employing a pin for a fastening means, as onbrooches and the like.

An object'of this invention is to provide a novel and improved latch forbrooches and similar articles, which is easy to lock and unlock.

Another object hereof isto provide a novel and improved latch means ofthe character mentioned, in which the pinpoint is shielded while thelatch is closed.

A further object of this invention is to provide a novel and improvedarticle of the type set forth which is reasonably cheap to manufacture,simple to manipulate andeflicient in carrying out the purposes for whichit is designed.

Other objects and advantages will become manifest as this disclosureproceeds.

To accomplish these objects, essentially, a pivoted pin is otherwisemoveably mounted on a frame carrying a socket for receiving the free endof the pin which is pointed, and means to prevent movement of the pinwhen within the socket.

In the accompanying drawings forming part of this application, similarcharacters of reference indicate corresponding parts in all the views.

Fig. 1 shows a closed latch embodying the teachings of this invention,partly in section.

Fig. 2 is a plan view of Fig. 1; the latter being a view which'also maybe described as a section taken along lines II.

Fig. 3 shows said latch in open condition.

Fig. 4 is a perspective view of the pin-point socket employed in thearticle illustrated.

Fig. 5 is a side view of Fig. 4.

Fig. 6 is a view similar to Fig. 3 embodiment of this invention.

Fig. 7 shows the article of Fig. 6 in closed condition, partly insection.

In the drawings, the numeral I0 designates an ornament carried on aframe indicated generally by the numeral II, which has associatedtherewith a swingable pointed pin I2, for attachment to a wearer'sgarment for instance. One end of the pin I2, is pivotally secured at I3to a link I4, while the other end of said pin is adapted to be receivedand housed in member designated generally by the numeral I5. The link I4is provided with a longitudinal slot I6, through which is positioned apin I'I, secured at its ends in a pair of bracket members I8 which arepart of the frame. It is evident that the link I4 is both slidable andswingable about said pin with respect to the frame element II. The framealso includes I9, which serves as a socket or track to receive the ofanother link I4 therein and maintain same against rotary movement aboutits axis pin I1. The element 20, may be so bent in slight convergentrelationship. with element II, that the fit of link I44 in .said socketis snug when shifted therein manually which may be facilitated by thetab I4. A second. tab I4" extending from said link, serves to limit themovement of the pointed pin I2ab0utitsaxis pin I3. The free end ofelement 20 and element II serve to limit the scope of rotary movement ofthe link I4 about its axis pin I'l.

The pin point housing I5, has a guide slot I5" which leads the point pinI2. into socket bore I5". Itis to be noted that axis pin I1 isintermediate the pin point socket I5 and I the. link socket IS, in closeproximity to the latter.. The. tininess of the various elements andparticularly in some constructions, the springiness of the pin memberI2, permits proper operation of this latch, whose mode of use will nowbe set forth.

Taking hold of the article in condition as shown in Fig. 3 when the pinI2 is free of socket I5, and link I4 is not engaged within socket I9,and in position substantially normal to frame II, said pin is laced inthe usualmanner through a fab-. ric. garment and swung about'pin I3 sothat the pointed end thereof may be placed within slot I5 of the housingI5 which shall guide its movement into the socket bore I5. By turningthe link I4 now, so that it shall lie in alignment with pin I2,

said link will enter its socket I9. The latch is now in closed conditionas illustrated in Fig. 1;

the article is securely worn, and the point of pin I2 is safely housed.To open the latch and remove the article from the wearer, take hold oftab I4 and slide the link out of socket I9, whereby pin I2 will movefurther into its socket bore I5 which is purposely made long enough forsuch purpose, and when said link I4 is free of member 29, it is swungaway from frame element I I' again into position as in Fig. 3, whereuponpin I2 will withdraw from socket I5, and the latch. will be open forwithdrawal of pin I2 from wearers garment.

In the embodiment illustrated in Figs. 6 and 7, the pin 22 is pivotallymounted at 23 to a link 24, which in turn is pivotally mounted. to thebracket 28. The axis pin 23 also carries thereon pivotally mounted, acam member 26 which is adapted to be shifted by handling prong 26', sothat said cam. frictionally engage the bracket member 28 to lock the pinagainst movement after the pointed end of the latter is set within thesocket member I5. The frame member is here indicated by the numeral 2|.

By turning cam 26 away from engagement with the bracket member 28 of thearticle of Fig. 7, the latch may be opened.

For purposes of definition in the claims, the bracket members l8 and 28,may be deemed as part of their respective frames.

This invention is capable of numerous forms and various applicationswithout departing from the essential features herein disclosed. It istherefore intended and desired that the specific;

description herein be'deemed illustrative and not restrictive, referencebeing had to the following claims rather than to the particularembodiments herein to indicate the scope of this invention.

I claim:

grip ed by 'said arms.

6;In an article of the character described, a

1 frame, a link having a longitudinal slot, an axis 1. In an article ofthe character described, a

frame, a link, means on the frame holdingsaid link in swingable andslidable relation to the frame, a pin pivotally secured at one of itsendsto the link; the axes of rotation of the pin with respect 'to thelink and of the linkwith respect to theframe being paralleL'a memberhaving a socket carried by the frame; the free end of the pin being"adapted to be positioned within said socket; and an element'carried bythe frame in engagement with said link whereby the link is heldagainstrotary movement and against sliding movement away from the socket; saidlink being'adapted to be'slid towards the socket until released from theengagement element and free for rotary movement about its axis on theframe; the pin, when its freeend is within the socket, moving furtherinto the socket during movement of the link away from the engagementelement, and the pin-becoming free of the socket, upon movement .cf thelink about its axis on the frame in a direction away from said socket.

'2. An article as defined in-claim 1,.including a stop means carried bythe link in the locus of movement of the pin with respect to said link;saidy'stop means being adapted to restrain rotary movement of the pinabout its pivotal connection on the link.

3. An article as'defined in claim 1, wherein the pin socket element isprovided with an entrance slot communicative with the socket bore; saidentrance 'slot lying in the locus of movement of the end portion or thefree end of thepin.

pin fixedly mounted on the frame and positioned through the slot,whereby the link is slidable on said axis pin in a direction normal tothe axis of said axis pin, and swingable about said axis,

,a pin pivotally secured at one of its ends to the link; the axis ofrotation of the pin with respect to the link and of the link withrespect to the frame, being parallel, a member having a socket carriedby the frame the: free end ofthe pin being adapted to be positionedwithinsaid socket;; and an element carried by the frame in engage-3 mentwith said link whereby the linkisheld against rotary movement,- andagainst sliding movement away from'the socket; saidlinkbeing adapted tobe slid towards the socket until re-.

leased from the engagement element-and free -for rotary movement about.itsaxis on the frame;

the pin, when its free end is Within the socket;

movement of the link about its axis on the'frame.
